SPECIFICATION forming part of Letters Patent No. 474,407, dated May 10,1892.

(No model.)

To all whom it may concern:

Be it known that I, FREEBORN F. RAYMOND, 2d, a citizen of the UnitedStates, and aresident of Newton, in the county of Middlesex and State ofMassachusetts, have invented a new and useful Improvement in HeelLoading and Compressing Machines, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming a part of this specification, in explaining itsnature.

The invention is an improvement upon that described in my applicationfor Letters Patent of the United States filed November 28, 1887, SerialNo. 256,297, and comprises various details of organization andconstruction whereby the machine is simplified, cheapen ed, and mademore efficient.

In the drawings, Figure l is a view in front elevation of a machinehaving the features of my invention. Fig. 2 is a view in side elevationthereof. Fig. 3 is a view in vertical central section of the central andupper parts of the machine. Figs. 4., 5, 6, 7, 8, and 9 are detailviews, to which reference is hereinafter made.

A represents the frame of the machine. It is practically integral or inone casting, and it comprises the side frames or sections A A the bed Aand the connecting or bracing plates or dowels, or both, A

Bis ahead, which is a cross-head, which has the bearing orguide-section 1) near each end and which slides in the perpendicularrecesses a in the guides b, which are bolted to the tops of the sideframes or sections A A The cross-head carries upon its under surface apressure-block O, a block 0, having a gang or group of awls c, a block Ghaving a gang or group of drivers 0, and an ejector C The cross-head isreciprocated by means of the crank-pins d upon gears D D, there beingone upon the outside of each side frame. The connecting-rods d and thepins or studs (1 upon the ends of the cross-head are either lutegraltherewith or attached thereto, as may be desired. The gears D aremounted upon a shaft (i and power is communicated to them by means ofthe pinions 6 upon the main shaft e, the said shaft having suitablebearings on the frame of the machine and carrying a heavy fiy-wheel E,which also serves as a pulley, and a clutch 6 There is mounted upon thetable A a column F, which carries or supports a die-carriage f. Thisdie-carriagef has asleevef, which fits the post, and the die-receivingrecesses f which receive the dies F, which are adapted to have a slightvertical movement in relation to the carriage, the extent of which islimited by the stops f f The dies F preferably are of the kind known assolid dies that is, they are made from one piece of metalhave thedie-cavity f opening downwardly, and the perforations or holes f inwhich the awls and drivers operate, and an ejector-plate f Thedie-carriage not only has a vertical movement upon the post or column,but it also has a rotary movement. This rotary movement maybecommunicated to it by hand or by power. I have represented it as movedby power by means of a spur-gear G, mounted upon its sleeve, a pinion g,mounted upon a shaft g in a position to engage the spungear and operatedor turned by means of the pulley g belt g and pulley g on the shaft G,the belt passing over guiding-pulleys 9 There may be a clutch interposedbetween the pulley g and the pinion g, if desired.

To look the die-carriage in position to register with thepressure-block, awls, and drivers, I employ an index H, attached to thesleeve of the carriage and having the latching-recesses h and the latchh, the end of which is held against the dial by a spring h in a mannerto force it into a recess in the dial when one comes in line therewith,and a lever 71, is connected with the latch to move itoutwardly or inopposition to the spring. This lever may also be connected with a clutchbetween the pulley g and the pinion g, whereby upon the movement of thelever to disengage the latch from a latching-recess the clutch shall becaused to engage the driven pulley g and the pinion to cause therotation of the pinion, and therefore of the carriage, and upon thereverse movement of the lever or the engagement of the latch with thelatching-recess to disengage the driven pulley from the pinion.

M M M represent stands mounted upon the bed A upon which are mounted theheelformers m m m These heel-formers are represented as provided withspindles entering holes in the stands and as adjustable vertically bymeans of the removable gage-blocks m There is also arranged upon the bedA a heel-blank lifter m for forcing heel-blanks into each die as it ismoved successively into position over it, and this heel-blank lifter ismounted upon a slide 172 which is moved vertically by means of the leverm It is desirable that the die-carriage and dies should be movablevertically in relation to the heelformers m m m in order that the diesmay be lifted from the formers sufficiently to be rotated and also inorder that the heels in the dies may be seated upon their formersbeforethe pressure-block comes in contact with the upper surface of its dieand the awls and nails are forced into their respective heelblanks, andit is also desirable that the carriage and dies be held during someportion of the upward movement of the cross-head positively, in orderthat the awls may be withdrawn from the heel-blank, and I haverepresented these movements as provided the carriage and dies by meansof a cam N upon the shaft d and a connecting-rod N, connecting the camwith the carriage, which extends upward through the hole n in the columnor post and is connected with the die-carriage in a manner to permit therotation of the carriage in relation thereto. I prefer that the cam hean edge-cam and that the rod have a roll n to bear against the same;also, that the rod have in addition a piece 71. in the form of a yoke,the end 01 0f which is arranged to extend beneath the projection nextending from the side of the cam when it is desired to hold thecarriage and dies against the upward draftof the awls. The campreferably is constructed to permit the carriage and the dies to movedownward slightly in advance of the downward movement of the cross-headand to then either hold the carriage down during the first part of theupward movement of the cross-head, or While the awls are being withdrawnfrom the heel, or at some point in the upward movement of the cross-headto hold the carriage stationary sufficiently to permit the awls to bewithdrawn and then to move it to its highest position. The length ofstroke or movement of the carriage is not as great as that of thecrosshead, it being necessary only to liftit enough to enable the diesto affect the formers.

If desired, in lieu of the former m a jack for holding a last orheel-support may be employed, and the nails, instead of being partlydriveninto the heel-blank by the drivers, may be driven through the sameto attach it to the soles of the bootor shoe. When the machine is soused, a die similar to that represented in Fig. 9 and provided with afront opening suitable to receive the shank of the shoe is employed. Themachine is represented as adapted to make but one reciprocation and thenstop.

The clutch comprises the member 0, which slides on the main shaft, andthe member 0,

which is one of the hubs of the fly-wheel. The member 0 is moved intoengagement with the member 0 by means of a treadle 0 andconnecting-lever 0 which, pivoted at 0 connects as a yoke with themovable member 0 of the clutch, and has an upward extension 0 providedwith the bent end 0 The lever is connected with the treadle by means ofthe toggle-links 0 0 and a rod 0 connecting the toggles with the lever.The bent end 0 bears against the face of the gear-wheel D during therotation of the wheel after the starting of the machine, and the memberoof the clutch is thus kept in engagement with the member 0'. To releasethe member 0 from the memhero, there is formed in the wheel D a hole orrecess 0 into which the bent end 0 of the lever o is drawn by the spring0 at the end of the upward movement of the cross-head, and to disengagethe section 0 of the clutch from the part 0 the links 0 0 of the toggleshould be of a length and should be so pivoted as not to be moved into astraight position by the treadle-that is, at the end of the downwardmovement of the treadle. they should still be bent, in order that theymay not move to lock the lever 0 with the two members of the clutchengaged. The treadle and its connections are well represented in Figs.1,2, 5, and 6.

The shaft G, which carries the pulley operating the belt 9 must becontinuously rotated, and I have represented it as so rotated by meansof a belt extending from a pulley thereon to a groove on the hub of thefly-wheel E. (See Figs. 1 and 2.)

The advantages of the construction arise largely from its simplicity,which enables the machine to be very strongly constructed, and from itsorganization, which permits it to be very efficient in use.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States- 1.
